Interactive communication system for downloading large amount data
First Claim
1. A data communication system comprising:
- an interactive communication system in which data is transmitted/received between a host server and a terminal;
a large amount data transmitting system for unidirectionally transmitting a large amount of data from the host server to said terminal; and
a data supplying apparatus for supplying data to be transmitted to said terminal to said interactive communication system when an amount of the data is less than a predetermined amount, and for supplying the data to be transmitted to said terminal to said large amount data transmitting system when the amount of the data is larger than the preset amount;
wherein said large amount data transmitting system comprises;
(i) storage means for temporarily storing large amount data supplied by the data supplying apparatus;
(ii) a timer for determining a scheduled transmission timing; and
(iii) transmitting means for transmitting the large amount data stored in said storage means to the terminal at the scheduled transmission timing.

Abstract
An information terminal transmits small amount data such as a command to a Web server on the internet to an asymmetric router via an interactive radio network. The asymmetric router transmits the command to the Web server via the internet. The asymmetric router transmits large amount data (for example, HTML formatted browser data) from the Web server to a data superimposing broadcast apparatus. The data superimposing broadcast apparatus determines a scheduled time of broadcasting according to a data amount. The scheduled time is transmitted to the information terminal via the asymmetric router and the interactive radio network. When the scheduled time comes, the large amount data is superimposed on an empty portion of a television signal, and is broadcasted. The information terminal carries out a predetermined processing operation whereby a broadcast receiving circuit is turned on, and the television signal on which the large amount data has been superimposed is received. The received data then can be displayed in a display device and the like. Therefore, even in a portable information terminal, it is possible to provide an interactive communication system which can transmit large amount data at a high speed.
